NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Condensed Consolidated Financial Statements

The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, are unaudited and reflect all adjustments of a normal recurring nature, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2023, is derived from the audited financial statements.

The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2023, filed on February 29, 2024. Results for the three and nine months ended September 30, 2024, are not necessarily indicative of results that may be attained in the future.

The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are affected by management’s application of accounting policies, as well as uncertainty in the current economic environment. Actual results could differ from those estimates.

Other Current Liabilities

The components of other current liabilities are included in the following table (in thousands):


	September 30, 2024		December 31, 2023
Operating lease liabilities	$	8,960	$	9,348
Vendor financed licenses	8,076		12,702
Accrued interest	3,124		9,172
Other	54,876		51,022
Total other current liabilities	$	75,036	$	82,244

Settlement Assets and Liabilities

Individuals and businesses settle their obligations to the Company’s various Biller clients using credit or debit cards or via automated clearing house (“ACH”) payments. The Company creates a receivable for the amount due from the credit or debit card processor and an offsetting payable to the client. Upon confirmation that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may (1) receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day, resulting in a settlement deposit on the Company’s books and (2) disburse funds to its clients in advance of receiving funds from the credit or debit card processor, resulting in a net settlement receivable position.

Table of contents

Off Balance Sheet Settlement Accounts

The Company also enters into agreements with certain Biller clients to process payment funds on their behalf. When an ACH or automated teller machine network payment transaction is processed, a transaction is initiated to withdraw funds from the designated source account and deposit them into a settlement account, which is a trust account maintained for the benefit of the Company’s clients. A simultaneous transaction is initiated to transfer funds from the settlement account to the intended destination account. These “back to back” transactions are designed to settle at the same time, usually overnight, such that the Company receives the funds from the source at the same time as it sends the funds to their destination. However, due to the transactions being with various financial institutions there may be timing differences that result in float balances. These funds are maintained in accounts for the benefit of the client which is separate from the Company’s corporate assets. As the Company does not take ownership of the funds, these settlement accounts are not included in the Company’s balance sheet. The Company is entitled to interest earned on the fund balances. The collection of interest on these settlement accounts is considered in the Company’s determination of its fee structure for clients and represents a portion of the payment for services performed by the Company. The amount of settlement funds as of September 30, 2024, and December 31, 2023, was $315.5 million and $273.2 million, respectively.

Fair Value

The fair value of the Company’s Credit Agreement approximates the carrying value due to the floating interest rate (Level 2 of the fair value hierarchy). The Company measures the fair value of its Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities. The fair value of the Company’s 5.750% Senior Notes due 2026 (“2026 Notes”) was $399.6 million and $398.5 million as of September 30, 2024, and December 31, 2023, respectively.

The fair values of cash and cash equivalents approximate the carrying values due to the short period of time to maturity (Level 2 of the fair value hierarchy).

Goodwill

In accordance with the Accounting Standards Codification ("ASC") 350, Intangibles – Goodwill and Other, the Company assesses goodwill for impairment annually during the fourth quarter of its fiscal year using October 1 balances or when there is evidence that events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. The Company evaluates goodwill at the reporting unit level and has identified its operating segments, Banks, Merchants, and Billers, as the reporting units. As of September 30, 2024, the Company's goodwill balance of $1.2 billion was allocated $671.7 million to Banks, $137.3 million to Merchants, and $417.0 million to Billers.

Recoverability of goodwill is measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value. The calculated fair value was substantially in excess of the current carrying value for all reporting units based upon the October 1, 2023, annual impairment test and there have been no indications of impairment in the subsequent periods.

Equity Method Investment

In July 2019, the Company invested $18.3 million for a 30% non-controlling financial interest in a payment technology and services company in India. The Company accounted for this investment using the equity method in accordance with ASC 323, Investments - Equity Method and Joint Ventures. The Company records its share of earnings and losses in the investment on a one-quarter lag basis. Accordingly, the Company recorded an investment of $19.6 million and $18.5 million, which is included in other noncurrent assets in the condensed consolidated balance sheet as of September 30, 2024, and December 31, 2023, respectively.

Recently Issued Accounting Standards Not Yet Effective

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, and early application is permitted. The Company is currently assessing the impact the adoption of ASU 2023-07 will have on its segment reporting disclosures.

2. Revenue

In accordance with ASC 606, Revenue From Contracts With Customers, revenue is recognized upon transfer of control of promised products and/or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products and services. Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities. See Note 9, Segment Information, for additional information, including disaggregation of revenue based on primary solution category.

Total receivables represent amounts billed and amounts earned that are to be billed in the future (i.e., accrued receivables). Included in accrued receivables are services, software as a service ("SaaS"), and platform as a service ("PaaS") revenues earned in the current period but billed in the following period, and amounts due under multi-year software license arrangements with extended payment terms for which the Company has an unconditional right to invoice and receive payment subsequent to invoicing.

The amount of unused borrowings actually available varies in accordance with the terms of the agreement.

Credit Agreement

On February 26, 2024, ACI Worldwide, Inc. (the “Company”) entered into a Refinance Amendment (the “Amendment”) to the Second Amended and Restated Credit Agreement, dated as of April 5, 2019 (as amended, restated, supplemented or otherwise modified from time to time, including by the Amendment, the “Credit Agreement”) among the Company, the subsidiary borrowers from time to time party thereto, the lenders from time to time party thereto, Bank of America, N.A., as administrative agent and a lender, BofA Securities, Inc., PNC Capital Markets LLC, Wells Fargo Securities, LLC, and TD Securities (USA) LLC, as Joint Lead Arrangers and Joint Bookrunners, and the other financial institutions party thereto.

The Amendment (i) provides a senior secured term loan facility (the “Term Loan Facility”) in an aggregate principal amount of $500 million, (ii) provides a senior secured revolving credit facility (the “Revolving Loan Facility” and together with the Term Loan Facility, the “Credit Facilities”) of up to $600 million, and (iii) extends the maturity date of the Facilities to February 26, 2029 (the “Maturity Date”), provided that if any of the Company’s 5.750% Senior Notes due 2026 are outstanding on the date that is 91 days before the maturity thereof (the “Springing Maturity Date”), and the Company does not have sufficient liquidity as of such date, the Maturity Date will be the Springing Maturity Date. The Revolving Loan Facility includes a $35 million sublimit for the issuance of standby letters of credit and a $20 million sublimit for swingline loans. Amounts repaid under the Revolving Facility may be reborrowed.

Borrowings under the Credit Facilities bear interest at a rate equal to, at borrower's option, either (A) a base rate determined by reference to the highest of (1) the rate of interest per annum publicly announced by Bank of America as its prime rate, (2) the federal funds effective rate plus 0.5%, (3) term Secured Overnight Financing Rate ("SOFR") plus 1%, and (4) 1% or (B) term SOFR for applicable interest period relevant to such borrowing, in each case plus an applicable margin. The applicable margin for borrowings under the Credit Facilities is, based on the calculation of the applicable consolidated total leverage ratio, between 0.5% to 1.5% with respect to base rate borrowings and between 1.5% and 2.5% with respect to term SOFR rate borrowings. Interest is due and payable monthly. The interest rate in effect for the Credit Facility as of September 30, 2024, was 6.70%.

The Company is also required to pay (a) a commitment fee related to the unutilized commitments under the Revolving Credit Facility, payable quarterly in arrears, (b) letter of credit fees on the maximum amount available to be drawn under all outstanding letters of credit in an amount equal to the applicable margin on SOFR rate borrowings under the Revolving Credit Facility on an annual basis, payable quarterly in arrears, and (c) customary fronting fees for the issuance of letters of credit fees and agency fees.

The Company’s subsidiaries, ACI Worldwide Corp. and ACI Payments, Inc. are co-borrowers under the Credit Agreement. The obligations of the borrowers under the Credit Facilities and the obligations of the Company and its subsidiaries under cash management arrangements entered into with lenders under the Credit Facilities (or affiliates thereof) are jointly and severally guaranteed by the Company and all of its existing and future material domestic subsidiaries, subject to certain exclusions. The obligations of the borrowers in respect of the Credit Facilities are secured by first-priority security interests in substantially all assets of the borrowers, including 100% of the capital stock of each domestic subsidiary of the borrower and 65% of the voting capital stock of each foreign subsidiary that is directly owned by a borrower, in each case subject to certain exclusions set forth in the Credit Agreement.

Table of contents

The Credit Agreement contains customary negative covenants that, among other things, restrict the Company’s ability to incur additional indebtedness, grant additional liens, and make certain acquisitions, investments, asset dispositions, and restricted payments. In addition, the Credit Agreement contains financial covenants that require the Company to maintain, as of the end of any fiscal quarter, (i) a consolidated total net leverage ratio of less than or equal to 4.25 to 1.00, (ii) a consolidated senior secured net leverage ratio of less than or equal to 3.75 to 1.00, and (iii) a minimum consolidated interest coverage ratio of greater than or equal to 3.00 to 1.00, in each case subject to certain exclusions as set forth in the Credit Agreement.

The awards have operating performance goals that include (i) adjusted EBITDA metrics and (ii) revenue growth rates as determined by the Company with a TSR multiplier up to plus or minus 20%. Up to 200% of the performance shares could be earned upon achievement of the performance goals, including the multiplier. On a quarterly basis, management evaluates the probability that the threshold performance goals will be achieved, if at all, and the anticipated level of attainment to determine the amount of compensation expense to record in the consolidated financial statements.

7. Earnings (Loss) Per Share

Basic earnings (loss) per share is computed in accordance with ASC 260, Earnings Per Share, based on weighted average outstanding common shares. Diluted earnings (loss) per share is computed based on basic weighted average outstanding common shares adjusted for the dilutive effect of stock options, RSUs, and certain contingently issuable shares for which performance targets have been achieved.

The following table reconciles the weighted average share amounts used to compute both basic and diluted earnings (loss) per share (in thousands):


	Three Months Ended September 30,		Nine Months Ended September 30,
	2024	2023	2024	2023
Weighted average shares outstanding:
Basic weighted average shares outstanding	104,770	108,667	105,651	108,428
Add: Dilutive effect of stock options and RSUs	1,248	266	901	—
Diluted weighted average shares outstanding	106,018	108,933	106,552	108,428

The diluted earnings (loss) per share computation excludes 1.0 million and 2.0 million options to purchase shares, RSUs, and contingently issuable shares during the three months ended September 30, 2024 and 2023, respectively, as their effect would be anti-dilutive. The diluted earnings (loss) per share computation excludes 1.2 million and 3.2 million options to purchase shares, RSUs, and contingently issuable shares during the nine months ended September 30, 2024 and 2023, respectively, as their effect would be anti-dilutive.

Common stock outstanding as of September 30, 2024, and December 31, 2023, was 104,870,815 and 108,077,738, respectively.

8. Other, Net

9. Segment Information

The Company reports financial performance based on its operating segments, Banks, Merchants, and Billers, and analyzes Segment Adjusted EBITDA as a measure of segment profitability.

The Company’s Chief Executive Officer is also the chief operating decision maker ("CODM"). The CODM, together with other senior management personnel, focus their review on consolidated financial information and the allocation of resources based on operating results, including revenues and Segment Adjusted EBITDA, for each segment, separate from corporate operations. No operating segments have been aggregated to form the reportable segments.

Table of contents

Revenue is attributed to the reportable segments based upon customer. Expenses are attributed to the reportable segments in one of three methods: (1) direct costs of the segment, (2) labor costs that can be attributed based upon time tracking for individual projects, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities.

Segment Adjusted EBITDA is the measure reported to the CODM for purposes of making decisions on allocating resources and assessing the performance of the Company’s segments, and, therefore, Segment Adjusted EBITDA is presented in conformity with ASC 280, Segment Reporting. Segment Adjusted EBITDA is defined as earnings (loss) from operations before interest, income tax expense (benefit), depreciation and amortization (“EBITDA”) adjusted to exclude net other income (expense).

Corporate and unallocated expenses includes global facilities and information technology costs and long-term product roadmap expenses in addition to corporate overhead costs that are not allocated to reportable segments. The overhead costs relate to human resources, finance, legal, accounting, and merger and acquisition activity. These costs along with depreciation and amortization and stock-based compensation are not considered when management evaluates segment performance.

10. Income Taxes

For the three and nine months ended September 30, 2024, the Company's effective tax rate was 24% and 25%, respectively. The Company reported a tax charge on pretax income for both the three and nine months ended September 30, 2024, with foreign entities recognizing earnings of $107.6 million and $148.1 million, respectively.

For the three and nine months ended September 30, 2023, the Company's effective tax rate was 19% and 83%, respectively. The Company reported a tax charge on pretax income for the three months ended September 30, 2023 and a tax benefit on pretax loss for the nine months ended September 30, 2023, with foreign entities recognizing earnings of $47.9 million and $64.9 million, respectively.

The Company’s effective tax rate could fluctuate on a quarterly basis due to the occurrence of significant and unusual or infrequent items, such as vesting of stock-based compensation or foreign currency gains and losses. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes.

The Organization for Economic Co-operation and Development Inclusive Framework on Base Erosion and Profit Shifting released Pillar Two Model Rules (“Pillar Two”) for a global minimum tax. Many countries have enacted certain aspects of the Pillar Two framework with effective dates in 2024. Entities operating in countries where Pillar Two has been enacted are required to estimate Pillar Two top-up tax obligations beginning in the first quarter of 2024.

For the nine months ended September 30, 2024, the Company did not have material Pillar Two top-up tax obligations impacting the Company’s estimated annual effective tax rate. The Company will continue to evaluate the impact of proposed and enacted legislation as new guidance becomes available.

As of September 30, 2024, and December 31, 2023, the amount of unrecognized tax benefits for uncertain tax positions was $21.0 million and $20.9 million, respectively, excluding related liabilities for interest and penalties of $0.4 million and $0.5 million, respectively.

The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $2.3 million, due to the settlement of various audits and the expiration of statutes of limitation.

11. Commitments and Contingencies

Legal Proceedings

In April 2021, ACH files associated with one of the Company's mortgage servicing customers were inadvertently transmitted into the ACH network during a test of the Company's payment processing system. The Company took immediate corrective action and issued reversing ACH files, restoring affected accounts.

The Company’s customer commenced an action for damages as a result of this event. The Company settled with the customer for the amount of $1.8 million, which will be funded by insurance carriers.

Funds received from or expected to be received from insurance carriers are generally subject to the respective carriers' reservation of rights.

The Company is from time to time subject to other claims, litigation and investigations. While the Company believes that none of the currently pending matters is reasonably likely to have a material adverse effect on it, there can be no assurance with respect thereto or future matters.

Global Economy and Inflation

Since 2022, the global economy has experienced high inflation, increased interest rates, and pressures on gross domestic product. While we believe our business is resilient and can generally weather unusually high levels of inflation, inflationary pressures have had some impact on our financial performance. Specifically, inflation impacted our interchange costs associated with the Biller segment.

Overview

ACI Worldwide powers digital payments for more than 6,000 organizations around the world. More than 1,000 of the largest banks and intermediaries, as well as thousands of global merchants, rely on ACI to execute $14 trillion each day in payments and securities. In addition, myriad organizations utilize our electronic bill presentment and payment services. Through our comprehensive suite of software solutions delivered on customers' premises, through the public cloud or through ACI's private cloud, we provide real-time, immediate payments capabilities and enable the industry's most complete omni-channel payments experience.

Our products are sold and supported directly and through distribution networks covering three geographic regions – the Americas; Europe, Middle East, and Africa (“EMEA”); and Asia Pacific. Each region has its own globally coordinated sales force, supplemented with local independent reseller and/or distributor networks. Our products and solutions are marketed under the ACI Worldwide brand and used globally by banks and intermediaries, merchants, and billers, such as third-party electronic payment processors, payment associations, switch interchanges, and a wide range of transaction-generating endpoints, including ATMs, merchant point-of-sale (“POS”) terminals, bank branches, mobile phones, tablets, corporations, and internet commerce sites.

We derive a majority of our revenues from domestic operations and believe we have large opportunities for growth in international markets, as well as continued expansion domestically in the United States. We also continue to maintain centers of expertise in Timisoara, Romania, and Pune and Bangalore in India, as well as key operational centers such as in Cape Town, South Africa and in multiple locations in the United States.

Table of contents

Our business and operating results are influenced by trends such as information technology spending levels, the growth rate of digital payments, mandated regulatory changes, and changes in the number and type of customers in the financial services industry, as well as economic growth, and purchasing habits.

Key trends that currently impact our strategies and operations include:

Increasing digital payment transaction volumes. The adoption of digital payments continues to accelerate, propelled by the digitization of cash, financial inclusion efforts of countries throughout the world, the Internet of Things, rapid growth of eCommerce and the adoption of real-time payments. COVID-19 further accelerated this growth as more people, governments, and businesses embraced digital payments - a change that has continued. We leverage the growth in transaction volumes through the licensing of new systems to customers whose older systems cannot handle increased volume, through the sale of capacity upgrades to existing customers, and through the scalability of our platform-based solutions.

Adoption of real-time payments. Expectations from both consumers and businesses are continuing to drive the payments world to more real-time delivery. This is bolstered by the new data-rich ISO 20022 messaging format, which is delivering greater value to banks and their customers. We are seeing global players with existing schemes working to expand capacity in anticipation of volume growth and new payment types. Mature markets, including India, the United Kingdom, Australia, Malaysia, Singapore, Thailand, and the Nordics, continue to accelerate innovation, especially in terms of overlay services and cross-border connectivity. The United States is driving real-time payments adoption through Zelle, TCH Real-Time Payments, and the FedNow service. We are seeing success with real-time payments in the Middle East as well, as they have started to renovate their payment systems from legacy payment types to the modern digital and real-time world. ACI's broad software portfolio, experience, and strategic partnerships with Mastercard, Microsoft, and Mindgate Solutions continue to position us as a leader in real-time payments, helping to drive seamless connectivity, increased security, and end-to-end modernization for organizations throughout the world.

Adoption of cloud technology. ACI has recognized the industry's technical inflection point in the transition from traditional on-premise infrastructure to the public cloud, and we are supporting our customers' cloud strategies. Public and private cloud technology innovations allow the financial services ecosystem to accelerate innovation and ensure scalability and resiliency while improving operating economics over time. As banks and intermediaries, merchants, and billers seek to transition their systems to make use of cloud technology, our investments and partnerships, as demonstrated by our product enablement and initial optimization onto Microsoft Azure, enable us to leverage those cloud technology benefits today and for the future while preserving ACI's fundamental base of performance, resiliency, and scalability.

Payments intelligence, fraud, and compliance. The accelerated adoption of real-time payments increases the urgency for industry-wide collaboration against fraud. As the threat of scams becomes a greater concern for remitting and receiving institutions, consumers are challenged with increased friction to prevent account take-over and criminals successfully persuading consumers to push transactions themselves, inadvertently, to mule accounts they have full control of, created with fake or synthetic identity, or simply "borrowed" with or without consent of the legit account holders. Regulators are beginning to litigate between consumers and financial institutions on the losses, and between emitting and receiving banks on the accountability for reimbursement. Banks and intermediaries, merchants, and billers are pursuing solutions to mitigate their risks while improving their customer experience, protecting their margins, and securing their revenue streams, especially with their new products and offerings. We continue to see opportunity for our advanced machine learning and network intelligence capabilities to stop criminals and enable frictionless legitimate business.

Omni-commerce. Shoppers are increasingly browsing, buying, and returning items across channels, including in-store, online, and mobile. COVID-19 accelerated this trend, leading to an increase in contactless payments, click and collect, and curbside collection. Merchants from all industries, including grocers, fuel and convenience stores, are being tasked with delivering seamless experiences that include pay-in-aisle, kiosks, mobile app payments, QR code payments, eCommerce, traditional and mobile POS, buy online pickup in-store (BOPIS), and buy online return in-store (BORIS). We believe there is significant opportunity to provide merchants with the tools to deliver a seamless, secure, personalized experience that creates loyalty and satisfaction, and drives conversion rates while protecting consumer data and preventing fraud.

Request for Payment (RfP). Markets across the world are introducing an innovative payments service called Request for Payment (RfP). This technology is known by different names in different markets: Collect payments in India, Request 2 Pay in Europe, Request To Pay (RTP) in the United Kingdom, or Request for Payment (RfP) in the United States. RfP offers secure messaging between consumers and billers or merchants, wherein a biller or merchant can request a payment from a consumer through the use of a trusted app, most likely a banking app. RfP is primarily being implemented on top of real-time payments, which are continuing to grow and flourish as countries around the world develop and launch their real-time schemes as noted

above. ACI is in a unique position to deliver this overlay service given our real-time payments software, our relationships with banks, merchants, and billers, and global real-time connectivity.

Several other factors related to our business may have a significant impact on our operating results from year to year. For example, the accounting rules governing the timing of revenue recognition are complex, and it can be difficult to estimate when we will recognize revenue generated by a given transaction. Factors such as creditworthiness of the customer and timing of transfer of control or acceptance of our products may cause revenues related to sales generated in one period to be deferred and recognized in later periods. For arrangements in which services revenue is deferred, related direct and incremental costs may also be deferred. Additionally, while the majority of our contracts are denominated in the U.S. dollar, a substantial portion of our sales are made, and some of our expenses are incurred, in the local currency of countries other than the United States. Fluctuations in currency exchange rates in a given period may result in the recognition of gains or losses for that period.

We continue to seek ways to grow through organic sources, partnerships, alliances, and acquisitions. We continually look for potential acquisitions designed to improve our solutions’ breadth or provide access to new markets. As part of our acquisition strategy, we seek acquisition candidates that are strategic, capable of being integrated into our operating environment, and accretive to our financial performance.

Backlog

Backlog is comprised of:

•Committed Backlog, which includes (1) contracted revenue that will be recognized in future periods (contracted but not recognized) from software license fees, maintenance fees, service fees, and SaaS and PaaS fees specified in executed contracts (including estimates of variable consideration if required under ASC 606, Revenue From Contracts With Customers) and included in the transaction price for those contracts, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods and (2) estimated future revenues from software license fees, maintenance fees, services fees, and SaaS and PaaS fees specified in executed contracts.

•Renewal Backlog, which includes estimated future revenues from assumed contract renewals to the extent we believe recognition of the related revenue will occur within the corresponding backlog period.

We have historically included assumed renewals in backlog estimates based upon automatic renewal provisions in the executed contract and our historic experience with customer renewal rates.

Our 60-month backlog estimates are derived using the following key assumptions:

•License arrangements are assumed to renew at the end of their committed term or under the renewal option stated in the contract at a rate consistent with historical experience. If the license arrangement includes extended payment terms, the renewal estimate is adjusted for the effects of a significant financing component.

•Maintenance fees are assumed to exist for the duration of the license term for those contracts in which the committed maintenance term is less than the committed license term.

•SaaS and PaaS arrangements are assumed to renew at the end of their committed term at a rate consistent with our historical experiences.

•Foreign currency exchange rates are assumed to remain constant over the 60-month backlog period for those contracts stated in currencies other than the U.S. dollar.

•Our pricing policies and practices are assumed to remain constant over the 60-month backlog period.

In computing our 60-month backlog estimate, the following items are specifically not taken into account:

•Anticipated increases in transaction, account, or processing volumes by our customers.

•Optional annual uplifts or inflationary increases in recurring fees.

•Services engagements, other than SaaS and PaaS arrangements, are not assumed to renew over the 60-month backlog period.

•The potential impact of consolidation activity within our markets and/or customers.

Table of contents

We review our customer renewal experience on an annual basis. The impact of this review and subsequent updates may result in a revision to the renewal assumptions used in computing the 60-month backlog estimates. In the event a significant revision to renewal assumptions is determined to be necessary, prior periods will be adjusted for comparability purposes.

The following table sets forth our 60-month backlog estimate, by reportable segment, as of September 30, 2024, June 30, 2024, March 31, 2024, and December 31, 2023 (in millions). Dollar amounts reflect foreign currency exchange rates as of each period end. This is a non-GAAP financial measure being presented to provide comparability across accounting periods. We believe this measure provides useful information to investors and others in understanding and evaluating our financial performance.

Estimates of future financial results require substantial judgment and are based on several assumptions, as described above. These assumptions may turn out to be inaccurate or wrong for reasons outside of management’s control. For example, our customers may attempt to renegotiate or terminate their contracts for many reasons, including mergers, changes in their financial condition, or general changes in economic conditions in the customer’s industry or geographic location. We may also experience delays in the development or delivery of products or services specified in customer contracts, which may cause the actual renewal rates and amounts to differ from historical experiences. Changes in foreign currency exchange rates may also impact the amount of revenue recognized in future periods. Accordingly, there can be no assurance that amounts included in backlog estimates will generate the specified revenues or that the actual revenues will be generated within the corresponding 60-month period. Additionally, because certain components of Committed Backlog and all of Renewal Backlog estimates are operating metrics, the estimates are not required to be subject to the same level of internal review or controls as contracted but not recognized Committed Backlog.

Revenues

Total revenue for the three months ended September 30, 2024, increased $88.7 million, or 24%, as compared to the same period in 2023.

•The impact of foreign currencies was not significant for the three months ended September 30, 2024, as compared to the same period in 2023.

Software as a Service (“SaaS”) and Platform as a Service (“PaaS”) Revenue

The Company’s SaaS arrangements allow customers to use certain software solutions (without taking possession of the software) in a single-tenant cloud environment on a subscription basis. The Company’s PaaS arrangements allow customers to use certain software solutions (without taking possession of the software) in a multi-tenant cloud environment on a subscription or consumption basis. Included in SaaS and PaaS revenue are fees paid by our customers for use of our Biller solutions. Biller-related fees may be paid by our clients or directly by their customers and may be a percentage of the underlying transaction amount, a fixed fee per executed transaction, or a monthly fee for each customer enrolled. SaaS and PaaS costs include payment card interchange fees, the amounts payable to banks and payment card processing fees, which are included in cost of revenue in the condensed consolidated statements of operations. All fees from SaaS and PaaS arrangements that do not qualify for treatment as a distinct performance obligation, which includes set-up fees, implementation or customization services, and product support services, are included in SaaS and PaaS revenue.

Table of contents

SaaS and PaaS revenue increased $12.0 million, or 6%, during the three months ended September 30, 2024, as compared to the same period in 2023.

•The increase was primarily driven by new customer go-lives since September 30, 2023, and higher transaction volumes during the three months ended September 30, 2024, as compared to the same period in 2023.

License Revenue

Customers purchase the right to license ACI software under multi-year, time-based software license arrangements that vary in length but are generally five years. Under these arrangements the software is installed at the customer’s location (i.e. on-premise). Within these agreements are specified capacity limits typically based on customer transaction volume. ACI employs measurement tools that monitor the number of transactions processed by customers and if contractually specified limits are exceeded, additional fees are charged for the overage. Capacity overages may occur at varying times throughout the term of the agreement depending on the product, the size of the customer, and the significance of customer transaction volume growth. Depending on specific circumstances, multiple overages or no overages may occur during the term of the agreement.

Included in license revenue are license and capacity fees that are payable at the inception of the agreement. License revenue also includes license and capacity fees payable annually, quarterly, or monthly due to negotiated customer payment terms. The Company recognizes revenue in advance of billings for software license arrangements with extended payment terms and adjusts for the effects of the financing component, if significant.

License revenue increased $77.8 million, or 98%, during the three months ended September 30, 2024, as compared to the same period in 2023.

•The increase was driven by license renewal timing as well as the relative size of new license and capacity events during the three months ended September 30, 2024, as compared to the same period in 2023.

Maintenance Revenue

Maintenance revenue includes standard, enhanced, and premium customer support and any post contract support fees received from customers for the provision of product support services.

Maintenance revenue decreased $4.4 million, or 8%, during the three months ended September 30, 2024, as compared to the same period in 2023.

•The decrease was primarily driven by customers reducing premium customer support and maintenance on non-strategic products during the three months ended September 30, 2024, as compared to the same period in 2023.

Services Revenue

Services revenue includes fees earned through implementation services and other professional services. Implementation services include product installations, product configurations, and custom software modifications (“CSMs”). Other professional services include business consultancy, technical consultancy, on-site support services, product education, and testing services. These services include new customer implementations as well as existing customer migrations to new products or new releases of existing products.

Services revenue increased $3.4 million, or 17%, during the three months ended September 30, 2024, as compared to the same period in 2023.

•The increase was primarily driven by the timing and magnitude of project-related work during the three months ended September 30, 2024, as compared to the same period in 2023.

Operating Expenses

Total operating expenses for the three months ended September 30, 2024, increased $28.1 million, or 9%, as compared to the same period in 2023.

•Total operating expenses for the three months ended September 30, 2024, included $5.6 million for cost reduction strategies and $0.3 million of other significant transaction-related expenses during the period, compared to $3.8 million for cost reduction strategies and $0.4 million of European data center migration expenses for the same period in 2023.

•The impact of foreign currencies was not significant for the three months ended September 30, 2024, as compared to the same period in 2023.

Table of contents

Table of contents

Merchants Segment Adjusted EBITDA increased $26.0 million for the nine months ended September 30, 2024, compared to the same period in 2023, due to a $16.3 million increase in revenue and a $9.7 million decrease in cash operating expense.

Liquidity and Capital Resources

General

Our primary liquidity needs are: (i) to fund normal operating expenses; (ii) to meet the interest and principal requirements of our outstanding indebtedness; and (iii) to fund acquisitions, capital expenditures, and lease payments. We believe these needs will be satisfied using cash flow generated by our operations, our cash and cash equivalents, and available borrowings under our revolving credit facility over the next 12 months and beyond.

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. As of September 30, 2024, we had $177.9 million of cash and cash equivalents, of which $68.2 million was held by our foreign subsidiaries. If these funds were needed for our operations in the United States, we may potentially be required to accrue and pay foreign and U.S. state income taxes to repatriate these funds. As of September 30, 2024, only the earnings in our Indian foreign subsidiaries are indefinitely reinvested. We are also permanently reinvested for outside book/tax basis difference related to foreign subsidiaries. These outside basis differences could reverse through sales of the foreign subsidiaries, as well as various other events, none of which are considered probable as of September 30, 2024.

Available Liquidity

The following table sets forth our available liquidity for the dates indicated (in thousands):


	September 30, 2024		December 31, 2023
Cash and cash equivalents	$	177,860	$	164,239
Availability under revolving credit facility	467,100		373,900
Total liquidity	$	644,960	$	538,139

The increase in total liquidity is primarily attributable to the $100.0 million increase in the maximum amount available under the revolving credit facility.

The Company and ACI Payments, Inc., a wholly owned subsidiary, maintain a $75.0 million uncommitted overdraft facility with Bank of America, N.A. The overdraft facility acts as a secured loan under the terms of the Credit Agreement to provide an additional funding mechanism for timing differences that can occur in the bill payment settlement process. As of September 30, 2024, the full $75.0 million was available.

On February 26, 2024, we entered into a Refinance Amendment (the “Amendment”) to the Second Amended and Restated Credit Agreement, dated as of April 5, 2019 (as amended, restated, supplemented or otherwise modified from time to time, including by the Amendment, the “Credit Agreement”) with ACI Worldwide Corp and ACI Payments, Inc. as co-borrowers, the lenders, and Bank of America N.A, as administrative agent and lender. The Amendment, among other things, (i) provides a senior secured term loan facility in an aggregate principal amount of $500 million, (ii) provides a senior secured revolving credit facility in an aggregate principal amount of $600 million, and (iii) extends the maturity date of the Facilities to February 26, 2029. The proceeds of the borrowings under the Amendment, together with cash on hand, were used to refinance all outstanding borrowings and replace all existing revolving commitments under the Credit Agreement immediately prior to the date of the Amendment and will be used to provide ongoing working capital and for other general corporate purposes.

Stock Repurchase Program

Our board approved a stock repurchase program authorizing the Company, as market and business conditions warrant, to acquire its common stock and periodically authorizes additional funds for the program. In June 2024, the board approved the repurchase of the Company's common stock of up to $400.0 million in place of the remaining purchase amounts previously authorized.

Table of contents

We repurchased 3,946,537 shares for $128.7 million under the program during the nine months ended September 30, 2024. Under the program to date, we have repurchased 62,867,837 shares for approximately $1.1 billion. As of September 30, 2024, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $372.3 million. See Note 6, Common Stock and Treasury Stock, to our unaudited condensed consolidated financial statements in Part I of this Form 10-Q for additional information.

Cash Flows

The following table sets forth summarized cash flow data for the periods indicated (in thousands):


	Nine Months Ended September 30,
	2024		2023
Net cash provided by (used by):
Operating activities	$	232,266	$	82,774
Investing activities	(31,641)		(30,527)
Financing activities	(170,445)		(47,773)

Cash Flows from Operating Activities

The primary source of operating cash flows is cash collections from our customers for purchase and renewal of licensed software products and various services including software and platform as a service, maintenance, and other professional services. Our primary uses of operating cash flows include employee expenditures, taxes, interest payments, and leased facilities.

Cash flows provided by operating activities were $149.5 million higher for the nine months ended September 30, 2024, compared to the same period in 2023. Our operating cash flows for the current quarter increased primarily due to $20.8 million less in income tax payments, as well as cash flows generated from $104.6 million in net income for the nine months ended September 30, 2024, as compared to a $1.1 million net loss for the same period in 2023.

Our cash flow from operating activities can fluctuate from period to period due to several factors, including: the timing of billings, which are typically higher in the third and fourth quarters in conjunction with sales timing and are variable based upon license renewal timing; collections, which will lag the quarters with higher billings; the timing and amounts of interest due to interest rate fluctuations and semi-annual Senior Notes interest payments; income tax and other payments; and our operating results.

Cash Flows from Investing Activities

The changes in cash flows from investing activities primarily relate to the timing of our purchases and investments in capital and other assets, including strategic acquisitions, that support our growth.

During the first nine months of 2024, we used cash of $31.6 million to purchase software, property, and equipment, as compared to $30.5 million during the same period in 2023.

Cash Flows from Financing Activities

The changes in cash flows from financing activities primarily relate to borrowings and repayments related to our debt instruments and other debt, stock repurchases, and net proceeds related to employee stock programs.

During the first nine months of 2024, we repaid a net $47.8 million on the Term Loan under the Amendment, $9.3 million of other debt payments, and $5.1 million of debt issuance costs. In addition, we used $127.7 million to repurchase common stock and $9.3 million for the repurchase of stock-based compensation awards for tax withholdings. We received net proceeds of $7.0 million on the Revolving Credit Facility, proceeds of $4.1 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended, and $17.7 million for settlement assets and liabilities due to processing timing. During the first nine months of 2023, we repaid $53.6 million on the Term Loan, $12.5 million of other debt payments, and $2.2 million of debt issuance costs. In addition, we used $4.2 million for the repurchase of stock-based compensation awards for tax withholdings, and $4.6 million for settlement assets and liabilities due to processing timing. We received net proceeds of $24.0 million on the Revolving Credit Facility, and proceeds of $5.3 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended.

Contractual Obligations and Commercial Commitments

For the nine months ended September 30, 2024, there have been no material changes to the contractual obligations and commercial commitments disclosed in Item 7 of our Form 10-K for the fiscal year ended December 31, 2023.

Critical Accounting Estimates

The preparation of the condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and other assumptions we believe to be proper and reasonable under the circumstances. We continually evaluate the appropriateness of estimates and assumptions used in the preparation of our condensed consolidated financial statements. Actual results could differ from those estimates.

The accounting policies that reflect our more significant estimates, judgments, and assumptions, and that we believe are the most critical to aid in fully understanding and evaluating our reported financial results, include the following:

•Revenue Recognition

•Intangible Assets and Goodwill

•Business Combinations

•Stock-Based Compensation

•Accounting for Income Taxes

During the nine months ended September 30, 2024, there were no significant changes to our critical accounting policies and estimates. Please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for our fiscal year ended December 31, 2023, for a more complete discussion of our critical accounting policies and estimates.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Excluding the impact of changes in interest rates, inflationary pressures, and the uncertainty in the global financial markets, there have been no material changes to our market risk for the nine months ended September 30, 2024. We conduct business in all parts of the world and are thereby exposed to market risks related to fluctuations in foreign currency exchange rates. The U.S. dollar is the single largest currency in which our revenue contracts are denominated. Any decline in the value of foreign currencies against the U.S. dollar results in our products and services being more expensive to a potential foreign customer. In those instances where our goods and services have already been sold, receivables may be more difficult to collect. Additionally, in jurisdictions where the revenue contracts are denominated in U.S. dollars and operating expenses are incurred in the local currency, any decline in the value of the U.S. dollar will have an unfavorable impact to operating margins. At times, we enter into revenue contracts that are denominated in the country’s local currency, primarily in Australia, Canada, the United Kingdom, other European countries, Brazil, India, and Singapore. This practice serves as a natural hedge to finance the local currency expenses incurred in those locations. We have not entered into any foreign currency hedging transactions. We do not purchase or hold any derivative financial instruments for speculation or arbitrage.

The primary objective of our cash investment policy is to preserve principal without significantly increasing risk. If we maintained similar cash investments for a period of one year based on our cash investments and interest rates at September 30, 2024, a hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest income by $0.2 million annually.

We had approximately $1.0 billion of debt outstanding as of September 30, 2024, with $602.9 million outstanding under our Credit Facility and $400.0 million in 2026 Notes. Our Credit Facility has a floating rate, which was 6.70% as of September 30, 2024. Our 2026 Notes are fixed-rate long-term debt obligations with a 5.750% interest rate. A hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest expense related to the Credit Facility by approximately $4.0 million.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Management, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded our disclosure controls and procedures are effective as of September 30, 2024.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act) during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1. LEGAL PROCEEDINGS

For a description of our material pending legal proceedings, please refer to Note 11, Commitments and Contingencies, in Part I of this Form 10-Q for additional information.

ITEM 1A. RISK FACTORS

There have been no material changes to the risk factors disclosed in Item 1A of our Form 10-K for the fiscal year ended December 31, 2023. Additional risks and uncertainties, including risks and uncertainties not presently known to us, or that we currently deem immaterial, could also have an adverse effect on our business, financial condition and/or results of operations.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

The following table provides information regarding our repurchases of common stock during the three months ended September 30, 2024:


Period	Total Number of Shares Purchased		Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Approximate Dollar Value of Shares that May Yet Be Purchased Under the Program
July 1, 2024 through July 31, 2024	203,380	(1)	$	39.23	203,317	$	372,314,000
August 1, 2024 through August 31, 2024	32,411	(1)	46.69		—	372,314,000
September 1, 2024 through September 30, 2024	29,744	(1)	48.58		—	372,314,000
Total	265,535		$	41.19	203,317

(1)Pursuant to our 2016 and 2020 Equity and Performance Incentive Plan, we granted RSUs. Under each arrangement, shares are issued without direct cost to the employee. During the three months ended September 30, 2024, 191,285 shares of RSUs vested. We withheld 62,218 of those shares to pay the employees’ portion of the applicable minimum payroll withholding.

In 2005, our board approved a stock repurchase program authorizing us, as market and business conditions warrant, to acquire our common stock and periodically authorize additional funds for the program, with the intention of using existing cash and cash equivalents to fund these repurchases. In June 2024, the board approved the repurchase of the Company's common stock of up to $400.0 million, in place of the remaining purchase amounts previously authorized. As of September 30, 2024, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $372.3 million.

There is no guarantee as to the exact number of shares we will repurchase. Repurchased shares are returned to the status of authorized but unissued shares of common stock. In March 2005, our board approved a plan under Rule 10b5-1 of the Securities Exchange Act of 1934 to facilitate the repurchase of shares of common stock under the existing stock repurchase program. Under our Rule 10b5-1 plan, we have delegated authority over the timing and amount of repurchases to an independent broker who does not have access to inside information about the Company. Rule 10b5-1 allows us, through the independent broker, to purchase shares at times when we ordinarily would not be in the market because of self-imposed trading blackout periods, such as the time immediately preceding the end of the fiscal quarter through a period of two business days following our quarterly earnings release.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and nine months ended September 30, 2024, the Company's effective tax rate was 24% and 25%, respectively. The Company reported a tax charge on pretax income for both the three and nine months ended September 30, 2024, with foreign entities recognizing earnings of $107.6 million and $148.1 million, respectively. For the three and nine months ended September 30, 2023, the Company's effective tax rate was 19% and 83%, respectively. The Company reported a tax charge on pretax income for the three months ended September 30, 2023 and a tax benefit on pretax loss for the nine months ended September 30, 2023, with foreign entities recognizing earnings of $47.9 million and $64.9 million, respectively. The Company’s effective tax rate could fluctuate on a quarterly basis due to the occurrence of significant and unusual or infrequent items, such as vesting of stock-based compensation or foreign currency gains and losses. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. The Organization for Economic Co-operation and Development Inclusive Framework on Base Erosion and Profit Shifting released Pillar Two Model Rules (“Pillar Two”) for a global minimum tax. Many countries have enacted certain aspects of the Pillar Two framework with effective dates in 2024. Entities operating in countries where Pillar Two has been enacted are required to estimate Pillar Two top-up tax obligations beginning in the first quarter of 2024. For the nine months ended September 30, 2024, the Company did not have material Pillar Two top-up tax obligations impacting the Company’s estimated annual effective tax rate. The Company will continue to evaluate the impact of proposed and enacted legislation as new guidance becomes available. As of September 30, 2024, and December 31, 2023, the amount of unrecognized tax benefits for uncertain tax positions was $21.0 million and $20.9 million, respectively, excluding related liabilities for interest and penalties of $0.4 million and $0.5 million, respectively. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $2.3 million, due to the settlement of various audits and the expiration of statutes of limitation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings In April 2021, ACH files associated with one of the Company's mortgage servicing customers were inadvertently transmitted into the ACH network during a test of the Company's payment processing system. The Company took immediate corrective action and issued reversing ACH files, restoring affected accounts. The Company’s customer commenced an action for damages as a result of this event. The Company settled with the customer for the amount of $1.8 million, which will be funded by insurance carriers. Funds received from or expected to be received from insurance carriers are generally subject to the respective carriers' reservation of rights. The Company is from time to time subject to other claims, litigation and investigations. While the Company believes that none of the currently pending matters is reasonably likely to have a material adverse effect on it, there can be no assurance with respect thereto or future matters.

Condensed Consolidated Financial Statements (Policies)	Sep. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, are unaudited and reflect all adjustments of a normal recurring nature, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2023, is derived from the audited financial statements. The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2023, filed on February 29, 2024. Results for the three and nine months ended September 30, 2024, are not necessarily indicative of results that may be attained in the future.
Use of Estimates	The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are affected by management’s application of accounting policies, as well as uncertainty in the current economic environment. Actual results could differ from those estimates.
Settlement Assets and Liabilities	Settlement Assets and Liabilities Individuals and businesses settle their obligations to the Company’s various Biller clients using credit or debit cards or via automated clearing house (“ACH”) payments. The Company creates a receivable for the amount due from the credit or debit card processor and an offsetting payable to the client. Upon confirmation that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may (1) receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day, resulting in a settlement deposit on the Company’s books and (2) disburse funds to its clients in advance of receiving funds from the credit or debit card processor, resulting in a net settlement receivable position.
Off Balance Sheet Settlement Accounts	Off Balance Sheet Settlement Accounts The Company also enters into agreements with certain Biller clients to process payment funds on their behalf. When an ACH or automated teller machine network payment transaction is processed, a transaction is initiated to withdraw funds from the designated source account and deposit them into a settlement account, which is a trust account maintained for the benefit of the Company’s clients. A simultaneous transaction is initiated to transfer funds from the settlement account to the intended destination account. These “back to back” transactions are designed to settle at the same time, usually overnight, such that the Company receives the funds from the source at the same time as it sends the funds to their destination. However, due to the transactions being with various financial institutions there may be timing differences that result in float balances. These funds are maintained in accounts for the benefit of the client which is separate from the Company’s corporate assets. As the Company does not take ownership of the funds, these settlement accounts are not included in the Company’s balance sheet. The Company is entitled to interest earned on the fund balances. The collection of interest on these settlement accounts is considered in the Company’s determination of its fee structure for clients and represents a portion of the payment for services performed by the Company.
Fair Value	Fair Value The fair value of the Company’s Credit Agreement approximates the carrying value due to the floating interest rate (Level 2 of the fair value hierarchy). The Company measures the fair value of its Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities.
Goodwill	Goodwill In accordance with the Accounting Standards Codification ("ASC") 350, Intangibles – Goodwill and Other, the Company assesses goodwill for impairment annually during the fourth quarter of its fiscal year using October 1 balances or when there is evidence that events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. The Company evaluates goodwill at the reporting unit level and has identified its operating segments, Banks, Merchants, and Billers, as the reporting units. Recoverability of goodwill is measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value. The calculated fair value was substantially in excess of the current carrying value for all reporting units based upon the October 1, 2023, annual impairment test and there have been no indications of impairment in the subsequent periods.
Equity Method Investment	Equity Method Investment In July 2019, the Company invested $18.3 million for a 30% non-controlling financial interest in a payment technology and services company in India. The Company accounted for this investment using the equity method in accordance with ASC 323, Investments - Equity Method and Joint Ventures. The Company records its share of earnings and losses in the investment on a one-quarter lag basis. Accordingly, the Company recorded an investment of $19.6 million and $18.5 million, which is included in other noncurrent assets in the condensed consolidated balance sheet as of September 30, 2024, and December 31, 2023, respectively.
Recently Issued Accounting Standards Not Yet Effective	Recently Issued Accounting Standards Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, and early application is permitted. The Company is currently assessing the impact the adoption of ASU 2023-07 will have on its segment reporting disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update will require disclosure of more disaggregated information about a reporting entity's effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and early application is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently assessing the impact the adoption of ASU 2023-09 will have on its income tax disclosures.
